Tools You’ll Need

Before we get started, let’s take a look at what tools you’ll need:

  • Lug Wrench
  • Jack
  • Jack Stands
  • Hammer
  • Punch
  • Replacement Wheel Studs
  • Thread Locker
  • Torque Wrench
  • Breaker Bar
  • Socket Set

Step-by-Step Guide

Now that you have everything you need, let’s start the wheel stud replacement process.

Step 1: Loosen the Lug Nuts

Loosen the lug nuts on the wheel you want to replace the studs on, using your lug wrench. Make sure you don’t remove them completely yet.

Step 2: Lift the Car

Once the lug nuts are loosened, use the jack to lift the car off the ground and secure it using jack stands. Make sure the car is stable before proceeding to the next step.

Step 3: Remove the Wheel

Remove the lug nuts and the wheel. Place the wheel in a safe spot nearby.

Step 4: Remove the Old Wheel Stud

On the back of the hub flange, locate the wheel stud you want to replace. Using a hammer and punch, hammer the wheel stud out of the hub until it is completely removed.

Step 5: Install the New Wheel Stud

Insert the new wheel stud into the hole in the hub where the old wheel stud was, making sure it is seated and aligned correctly. Thread a lug nut onto the end of the new wheel stud to hold it in place.

Step 6: Tighten the Lug Nut

Using the breaker bar and socket set, tighten the lug nut to a torque of 60-80 lb-ft.

Step 7: Repeat Steps 4-6 for Other Wheel Studs

Repeat steps 4-6 for any other wheel studs that require replacement on the same wheel.

Step 9: Tighten the Lug Nuts

Using the torque wrench, tighten the lug nuts to the manufacturer’s recommended torque value. Make sure to tighten the lug nuts in a star pattern to ensure even tightening.

Step 10: Lower the Car

Using the jack, lower the car to the ground. Once it is fully lowered, use the lug wrench to tighten the lug nuts one final time.

Step 11: Test Drive

Take your car for a test drive to ensure that everything is functioning correctly.

Congratulations! You have successfully replaced the wheel studs on your 2015 Subaru STI.
